Mixtures of High-Speed and 
Low-Speed Networks
This c hapter p resents sup p orted  c onfig urations using  hig h-sp eed  and 
low-sp eed c onnec tions on the same DEFINITY AUDIX system. The DEFINITY 
AUDIX system c an sup p ort all three typ es of networking  c onnec tions. The 
c onnec tion typ es (DCP Mode 1, DCP Mode 2, and  DCP Mod e 3) are d ynamic  
and  c an c hang e on a c all-b y-c all b asis to d ifferent systems for eac h networking  
p ort. Eac h networking  p ort c an only sup p ort one DCP mode at any one time b ut 
c an c hang e mod es for the next c all. Ad d itional hard ware is always need ed  for 
DCP Mod e 2 c onnec tions. 
For examp le, a DEFINITY AUDIX system c ould  use the following  c omb ination of 
network c onnec tions:
nDCP Mod e 2 c onnec tion to an AUDIX R1 system or to an Intuity AUDIX 
system that uses an RS-232 c onnec tion or to another DEFINITY AUDIX 
system
nDCP Mod e 1 and /or DCP Mod e 3 c onnec tion to another DEFINITY AUDIX 
system, an Intuity AUDIX system, or an AUDIX R1 system 
Hig h-sp eed  (DCP Mod e 1/ DCP Mod e 3) c onnec tivity is the p referred  c onnec tion 
type if high-sp eed  fac ilities are availab le b etween loc ations. 
Considerations
If a c ustomer is c onsid ering  using  DCP Mod e 3 c onnec tions in their DEFINITY 
AUDIX network, keep  the following  in mind :
nWhen b oth high-sp eed  networking  and  low-sp eed networking  are used , 
low-sp eed networking  c an ind uc e d elays for high-sp eed  networking .

nTo p erform a network loop around  test, there must b e two dig ital 
networking  p orts on the mac hine b eing  tested, and  b oth p orts must use 
the same DCP mode. One port d oes not allow loopb ac k testing .
nExternal DCP Mod e 2 eq uip ment (mod em, ADU, TN726, 7400A, and  
c ab ling) c annot b e tested  using  a network loop around  test unless the 
DEFINITY AUDIX system has all DCP Mod e 2 eq uipment for two 
networking ports.

Digital Network Planning
Before you install and  ad minister DEFINITY AUDIX d ig ital networking , you must 
p lan the p roc ess. This c hap ter provid es worksheets and  information to help you 
c ollec t, p lan, and  rec ord  d ig ital networking  information. 
DEFINITY AUDIX d ig ital networking  req uires two levels of p lanning :
nPrep urc hase p lanning  p erformed  b y the d esign c enter, the ac c ount team, 
and  the c ustomer
nAd ministration p lanning  p erformed  b y the c ustomer, the network 
ad ministrator, and  the ac c ount team
This c hapter p rovid es an overview of the d esig n p roc ess and  worksheets to aid  
you with DEFINITY AUDIX d ig ital network p lanning . The worksheets p resented  in 
this c hap ter are an aid  for interac ting  with your d esig n c enter and for help ing  you 
und erstand  the ad ministration proc ess. Work with the d esig n c enter to c omp lete

Design Center
All digital networks must be designed and technically assured by the GBCS 
Desig n Center, International Tec hnic al Assistanc e Center (ITAC), or Centers of 
Exc ellenc e (COE). The c ustomer, ac c ount team, and  d esig n c enter must work 
tog ether to c omp lete the p rep lanning proc ess. Installation and  maintenanc e 
sup p ort of d igital networks will b e offered  only to those c ustomers/ac c ount teams 
who follow this d esig n p roc ess.
To develop a digital network design, the design center must gather or receive 
information ab out a c ustomer site and  the networking  req uirements of the 
c ustomer. Some of the information g athered  and  p rovid ed  b y the d esig n c enter 
inc lud es:
nInformation on installed  DEFINITY AUDIX systems, Intuity AUDIX systems, 
AUDIX R1V5 or later systems, and  switc hes
nTransmission issues c onc erning  network ac c ess b etween networked  
systems for inc oming  and  outg oing  messag es
nTraffic  stud ies to d etermine if the p rop osed  network is feasib le with the 
p rop osed  eq uip ment and  d ata rates inc lud ing :
— The p erc entage of voic e messag es that will b e exc hang ed  remotely
